# 字符串的三种表示方式:单引，双引，三引
str01 = "hello world"
str02 = 'hello world'
print(str01, str02)
# 打印: Hello,I'm fine.
# print('Hello,I'm fine.') # 报错，符号冲突
print("hello,I'm fine.") # 正常打印
# 打印: Hello,I'm "dc", fine.
# ---------三引号的功能--------
str03 = '''Hello,I'm "dc", fine''' # 解决符号冲突
print(str03)
# 字符串原样表示
